1. How much is a Bicycle helmet?

The price of a Bicycle helmet varies from factors such as brands, models, materials, functions, and sales channels, so a fixed price cannot be given.Generally speaking, the price of Bicycle helmets ranges from tens of yuan to hundreds of yuan.Economic helmet prices may be around tens of yuan, suitable for consumers with limited daily cycling or budget.And high -end brands, professional -level or more helmets with more special features, such as a helmet with a full helmet, wind mirror or communication system, the price may reach hundreds of yuan or even higher.

2. The difference between expensive and cheap Bicycle helmets

1. Materials and crafts

Low -priced helmets often use cheaper materials. For example, EPS polycopenyethylene foam is used as a lining material. The quality of the shell material and beam band may be unsatisfactory.These materials may be lacking in protective performance and durability.

High -priced helmets may use more high -grade shell materials, such as carbon fiber, and more comfortable lining and bands.These materials not only have better protection performance, but also provide better wearing comfort and durability.

2. design and function

The design of low -cost helmets is relatively simple and the function is relatively basic, which mainly meets basic head protection needs.

High -priced helmets may apply more advanced design concepts and functions, such as pneumatic design, MIPS buffer technology, etc. to improve wearing experience and security.These technologies can effectively reduce the rotation power of the head in the impact, thereby better protecting the head from damage.

3. brand and premium

Due to its brand value and market positioning, its product prices are usually relatively high.brand premium is an important factor in high -priced helmets higher than low -priced helmets.In addition, well -known brands often pay more attention to product quality and after -sales service, so their helmets are usually more guaranteed in terms of quality and reputation.

4. Safety standards and certification

Although low -priced helmets also meet basic security standards, they may perform poorly in some high -level security testing and certification.

High -priced helmets often pass more and higher Levels of security testing and certification, such as CE and CPSC to ensure their safety performance in actual use.
